Python program to build flashcard using class in Python

Last Updated : 06 Sep, 2024

In this article, we will see how to build a flashcard using class in python. A flashcard is a card having information on both sides, which can be used as an aid in memoization. Flashcards usually have a question on one side and an answer on the other. Particularly in this article, we are going to create flashcards that will be having a word and its meaning.

Let's see some examples of flashcard:

Example 1:

Approach :

Take the word and its meaning as input from the user.
Create a class named flashcard, use the __init__() function to assign values for Word and Meaning.
Now we use the __str__() function to return a string that contains the word and meaning.
Store the returned strings in a list named flash.
Use a while loop to print all the stored flashcards.

Below is the full implementation:

Python

class flashcard:
    def __init__(self, word, meaning):
        self.word = word
        self.meaning = meaning
    def __str__(self):
      
        #we will return a string 
        return self.word+' ( '+self.meaning+' )'
      
flash = []
print("welcome to flashcard application")

#the following loop will be repeated until
#user stops to add the flashcards
while(True):
    word = input("enter the name you want to add to flashcard : ")
    meaning = input("enter the meaning of the word : ")
    
    flash.append(flashcard(word, meaning))
    option = int(input("enter 0 , if you want to add another flashcard : "))
    
    if(option):
        break
        
# printing all the flashcards 
print("\nYour flashcards")
for i in flash:
    print(">", i)

Output:

Time Complexity : O(n)
Space Complexity : O(n)

Example 2:

Approach :

Create a class named flashcard.
Initialize dictionary fruits using __init__() method.
Now randomly choose a pair from fruits using choice() method and store the key in variable fruit and value in variable color.
Now prompt the user to answer the color of the randomly chosen fruit.
If correct print correct else print wrong.

Python

import random

class flashcard:
    def __init__(self):
      
        self.fruits={'apple':'red',
                     'orange':'orange',
                     'watermelon':'green',
                     'banana':'yellow'}
        
    def quiz(self):
        while (True):
          
            fruit, color = random.choice(list(self.fruits.items()))
            
            print("What is the color of {}".format(fruit))
            user_answer = input()
            
            if(user_answer.lower() == color):
                print("Correct answer")
            else:
                print("Wrong answer")
                
            option = int(input("enter 0 , if you want to play again : "))
            if (option):
                break

print("welcome to fruit quiz ")
fc=flashcard()
fc.quiz()
